We describe a patient with an exophytic oral lesion diagnosed as verrucous carcinoma. The lesion existed without metastases, at least 5 years. Local excisions led to recurrences and continuous expansion. Scalpel biopsies for histopathological and polymerase chain reaction examination were obtained from characteristic regions of the lesion. Brush biopsies for exfoliative cytology (EC) were taken, in order to screen the mucosal area covered by the lesion. After Feulgen restaining of the smears, nuclear DNA contents were measured using a TV image analysis system. An exophytic lesion of the buccal mucosa was diagnosed as low-grade malignant through histopathology and EC combined with DNA-image cytometry (peritetraploid DNA-aneuploidy). Due to almost normal microscopic appearance of the epithelium of verrucous carcinoma, thorough cytological/DNA-cytometric and histological examinations are needed. Brush biopsies of such neoplastic oral lesions showing DNA-aneuploidy with peritetraploid stemlines should be used for diagnosis and follow-up examination of these patients.
